PLOW.

To all whom it may concern:

Be it known that I, JEssE A. PANKEY, citizen of the United States,residing at Minden, in the county of Kemper and State of Mississippi,have invented certain new and useful Improvements in Plows, of which thefollowing is a specification.

This invention relates generally to implements for tilling the soil, andrefers particularly to a novel construction of plow.

The invention has for an object the provision of a plow which is formedof a few number of parts which are arranged substantially andconstructed so as to produce a strong and durable device of this naturewhich is more applicable to practical use than devices of this natureheretofore manufactured.

The invention has for another object the provision of means in a plowconstruction for adjusting the pitch of the plow foot or standard inorder to dispose the plow car ried thereby at the proper angle incidentto the work which is to be performed.

The invention further contemplates the provision of a plow foot whichadmits of the quick detachment of points and the like thereto andwhichwill rigidly secure the same in position when such are employed.

For a full understanding of the invention reference is to be had to thefollowing description and accompanying drawings, in which Figure 1 isa'perspective view of a double moldboard plow constructed according tothis invention, and Fig. 2 is a side elevation of the lower end of thefoot thereof. Fig. 3 is a side elevation of the foot of the frame havinga turn plow applied thereto, and Fig. 4 is a bottom plan view of thesame.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawing by the samereference characters.

Referring to the drawing in which is disclosed an embodiment of theinvention the numeral 10 designates a plow beam which is preferablyformed of steel and which is The plow beam 10 is reduced at its rearlower extremity to engage between the companion bars 12 which aredisposed in parallel and in spaced relation to form the standard of theplow, the beam 10 being retained between the companion bars 12 by thepositioning of a bolt 13 transversely through the Specification ofLetters Patent.

standard 12 and the beam 10. This positioning of the bolt 13 admits ofthe pivotal movement of the beam 10 which is regulated and retained inadjusted position by the employment of a pair of adjusting bars 14 whichare connected to the highest point of the arch 11 of the beam 10 andextended b-ackwardly therefrom. The adjusting bars 14 are secured attheir rear extremities to the handles 15 of the plow which extenddownwardly and are pivotally 1 engaged upon the bolt 13 outwardly of thecompanion bars 12.

The standard is provided at its upper extremity, the companion barswhich form the same being converged, with an elongated slot 16 throughwhich a clamping bolt 17 is engaged which is adjustably positionedthrough longitudinal slots 18 formed in the adjusting bars 14 inparallel relation. The lower extremity of the standard 12 is extendedforwardly in the usual manner to form a foot 19 which carries a frog 20which is integrally formed therewith, the same being extended outwardlyfrom the forward edges of the companion bars which form the standard 12.The frog 20 is provided with a share 21 having diverged ears 22 whichengage with the frog 20 to support the share 21 thereon by suitablebolts or the like, the frog 20 also serving as a support for a doublemold-board 23 which flares upwardly and outwardly from the sides of thestandard 12. The double moldboard 23 is provided cen-. t-rally with anaperture which registers with the openings between spaced companion bars12 for the reception of a clamping bolt 24: which is extended rearwardlythrough the double moldboard 23 and standard 12 and clamped in positionby means of a suitable nut 25.

In connection with the device a depth runner is employed which comprisesan elongated frame 26 which is longitudinally slotted and through whichis vertically disposed a plate 27 having vertically disposed slotsformed adjacent the opposite ends thereof and in parallel relationthrough which are engaged clamping bolts'28 for securing the plate 27 inadjusted position. The forward end of the frame 26 is curved upwardly atan abrupt angle and abutted against the rear edges of the companion bars12 where it is provided with adepending web 29 which is aperturedtherethrough in order to secure the frame 26 to the standard 12. Inconjunction with this form of plow frame a turn plow is provided and amodified form of the plow support especially adapted to thisconstruction. A standard which comprises spaced companion bars istransversely apertured for the reception of a bolt 31 which engagesthrough a lug 32 stamped and turned inwardly from the share 33 which isdisposed at a rearward angle to the standard 30. The share 33 isprovided with a landside 34 which extends rearwardly from the forwardedge thereof directly against the inner side of the standard 30 and isengaged thereagainstby the end of the bolt 31 which passes through thelug 32. The landside 34 extends upwardly against the standard 30 and isfurther secured in position by the provision of a second bolt 35 whichis engaged through the landside 3 1 and through the companion bars whichform the standard 30. A turnshovel 36 is mounted upon the lower portionof the share 33 and is suitably secured thereon by bolts or the like,while a moldboard of common formation is engaged upon the upper end ofthe share 33 and curved upwardly and outwardly therefrom. The landside34: is suitably apertured for the reception of bolts or the like tosupport a bar 38 disposed between the share 33 and the landside 34. Inthis construction it is readily observed that the standard 12 may beadjusted to various angles by loosening the clamping bolt and swingingthe standard into the desired angle, the clamping bolt 17 being carriedlongitudinally within the slots 18 formed in the adjusting bars 14 andthe longitudinal slot 16 formed in the upper extremities of thecompanion bars which form the standard 12. The depth runner may also beadjusted by manipulating the clamping bolts 28 to permit of the verticaladjustment of the plate 27 in accordance with the desired depth to whichthe plate 27 is adapted to be engaged.

Having thus described the invention what is claimed as new is 1. Adevice as specified comprising an arched beam, a standard pivotallyengaged with said beam, said standard having an elongated slot in theupper end of the same, handles rearwardly dlverged from said standard atthe point of engagement of said beam, a pair of adjusting barshorizontally disposed between said beam and said handles, said barshaving longitudinal slots formed in the same, a clamping bolt engagedthrough said clamping bars and through the elongated slot formed in theupper end of said standard, a frog positioned upon the lower end of saidstandard, a share carried by said frog and a double moldboard carried bysaid frog and said standard.

2. A plow including a beam having its rear end curved downwardly, aforked standard secured to said beam, the arms of said standard beingengaged against the sides of said beam, a pivot pin secured through saidstandard and said beam, a pair of handles engaged against said standardand secured to said pin, a pair of companion bars disposed between saidbeam and said handles, said standard being extended between said bars,and a clamping bolt adjustably secured through said bars and saidstandard.

In testimony whereof I afiix my signature in presence of two witnesses.
